The website reminds me of when Ellen Degeneres had Hugh Laurie on her show and held a contest of sorts to see who could understand more slang--Hugh gave Ellen examples of British slang, and she had to guess the words' meanings; Ellen gave Hugh examples of American slang, and he had to guess the words' meanings. You can see the video below, or you can go here and see it on YouTube.
So let's table ideas on slang words and waffle on about sweet fanny adams until we're zonked or until some bladdered tosser who's legging it brasses us off by interrupting our chin wag. It'll be awesome! (Anyone who's British can feel free to openly mock my inability to apply newly learned slang correctly.)
